Contributions

Future contributions

All contributions are welcome. The code can very much be improved, be it corrections, comments, code cleaning...etc.

If you are familiar with other programming languages, you are very welcome to send me your implemention of the concepts seen in class and I will post them in this repo.

Past contributions

Thank you to Sébastien PLAASCH ([email protected]) for providing the R code, as well as making the app accessible online via browser. Sébastien specifically provided heavy comments in the code in order to make it understandable to newcomers.

For any question/remark, please feel free to email me at [email protected] .

cryptography-code's Issues

Fix error when no key is entered

In the Vigenere (de)cipher for the R code

The following error message is displayed:
Error: An error has occurred. Check your logs or contact the app author for clarification.

This happens when no key is entered in the KEY textbox. Would be nice to add a more useful message such as "Please enter a key in the KEY textbox".

@Plaaschou ?

Implement euler's function

Finish RSA
